What is the total amount of heat energy transfer required to change 0.86 mol of ice at -22 oC to steam at 100 oC?
Explain what happens upon addition to a strong acid to the following equilibrium without using the Le Chatelier principle. What happens upon addition of a strong base
Use qualitative molecular orbital theory to explain why Na2O2 is diamagnetic and KO2 is paramagnetic (use the appropriate diagram from the notes. Use MO to explain the nature of the oxygen-oxygen bond in the complex anions). What is the oxygen-oxy..
A constant pressure calorimeter having a heat capacity of 74.2 kJ/K is used to measure the energy released from burning a compound in excess oxygen to form CO2(g) and H2O(l).
If 20.8 ml of base is required to reach the equivalence point, what is the concentration of the acid?
